To all whomz't mayconcem:

Beitknown that I, MILToN E. WINANS, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and use-- fullmprovements in Bench-Vises, of which the following is a specification.

The objects ofthis invention are to provide an improved bench vise in which there are no projections from the front jaw, such as would be in the way of the workman,and

in which the front .jaw is. stationary and thus always supported with the same firmness an'd solidity; to enabl-e'th'e position of;

the adjustable rear jaw to .be quickly and readily changed; to hold it in position,when.'

adjusted,1by supporting means directlyback of its working face;v to provide for this purpose a'pawl or ratchet'and an eccentric, cam' or the like; to operate said eccentric or cam by alever whichis thus set back fromt-he front of the vise and has to be swung through only a short arc; to utilize said lever for releasing and, engaging; the pawl or ratchet with its rack teeth to also utilize it for slid-.-

front of the vise, or next the workman, in I use, and preferably it does not project materially beyond thebase of the' body portion, I

so that it is firmlyand rigidly supported.

Since this jaw is fixed and does not project materially from the front of the vise, there 7 is nothing to obstruct free access to the vise or get in the way of the workman.

The sides ofthe slideway '2, which extendrearward from the fixed front jaw 3, are

2 a recess or chamber 8 which opens through the rear end ofthe jaw. A shaft 9 extends transversely of the movable jaw through said recess or chamber 8 and has a squared outer end 10 adapted to receive a handle or lever 11. I Said shaft also extends through a pawl 12 located in the recess or chamber 8,

' said pawl occupying an inclined position'as shown in Fig. '3, with its rear end adaptedto engage the top of the slideway. 2. Preferabl v' said slideway is notchedfto provide a lraclc 13 and the underside of the rear end of the pawl '12 .is correspondingly toothed to engage said notches. The shaft 9 iseccentric l with respect either to the pawll2 or to its bearings in the movable jawfso fthat turn-- ing of the shaft willtend toproject the pawl. 1 from the chamber or recess 8 orv retract it 'into'the same, according tothe direction; of:

turning; I have shown the middle portion .14 ofthe shaft, which extends through the v pawl, as eccentric with'respect to. the rest of. detail section, on, l ne 4- 4,

the shaft, and the end of the shaft. away from its square end 10 provided with are movable sleeve 15 held in. place by a screw 16, so that'theshaft can be removed .and re-.

placed, although it will ,be understood that these details may be varied as desired.

In operation, the movable jawnis slid up against a piece of work placed in the jaws, as shown in 'Flg. 3, andthen the shaft '9 .is

turned by its handle or lever 11 in theproper;

direction to-force thekpawl 12 rearward.,105

Said pawl, however, being in engagement 7 by its toothedlower rear end with .thelrack teeth of the slideway, the turning action.

ofthe: shaft: 9 will force the slidablejaw againstthe worktogrip thesame; The

P re i th "obta e n be very gre ag" because of its wedging quality, and will hol without slipping at any pointto which the shaft is turned by meansornslever '11?" V 5 The work is thus very readily and forcibly clamped, and is easily and quickly released when desired, an added advantage of the structurebeingthat the handle or"lever"11"' may-be swung through'onlyasmall angular distance, less than 90. It should also be noted that thepreferred arrangement 1 is such that in clamping the handlei'orlever swings away from the work.

Preferably means are provided for automatically lifting the pawl or ratchet '12? when the same is released, and I have shown. such .means'asa pin 17 projecting from'the side of the pawl or ratchet and adapted to be engaged by a projection 18 on the handle 20: or lever 11, 'said projection:being'located so that as the levier'is' swung to turn the shaft 9 so1that its cam" or eccentric portion retracts thepawl, said projection will engage beneath the pin 17., as shown in Figs. 1 and 2; To limit such uplifting of the pawl 12,

a lug19, projects from the'rear end of'the movable-jaw into the path of the "pinnll' as it moy es upward 'in lifting the pawl.

This'furth'ermore enables the handle or lever 330i 11 to beutilize'd for-sliding the movable j aw as well as for locking and releasing it,-for

it'will be'notedthat'when the lever or han dle isthrown forward .torelease the pawl and raise;:thesamebbntinued pressure will slide themovable jaw toward-the fixed jaw.
